midiKEY - a proposed wireless input system based on a novel stretch sensor technology
Built on my kitchen table, bedroom floor, and research class bench during senior year of high school. Conductive thread crocheted into strands that change resistance when the geometry is deformed by stretching. Input from each sensor's stretched or unstretched state is decoded into an alphanumeric character. Full paper here.
